From e9f9c8262a85bfe5ab657b38b8c0132c86c3722e Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Fri, 13 Jul 2012 15:22:43 +0900 Subject: ARM: S3C64XX: Add a new dma request id for device tree based dma channel lookup Commit 4972a80e16a2 (ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers) introduced a new member 'dt_dmach_prop' in the struct samsung_dma_info which is used to specify the dma channel number property as obtained from the device tree. It also introduced a new dma request id 'DMACH_DT_PROP' to indicate that a device tree node property represting the dma channel is available in 'struct samsung_dma_info'. Add dma request id 'DMACH_DT_PROP' in s3c64xx dma channel id list in order to maintain compatibility to the changes in the Samsung dma wrappper operations.
